Senior AI Engineer

Teak is reinventing refunds with their innovative SaaS embedded refund protection platform. As a Senior AI Engineer, you'll lead the development of AI-native capabilities, architecting systems that integrate with existing APIs to enhance the purchasing experience.

Responsibilities:

• Design, build, and maintain production-grade agentic systems, multi-agent orchestration, specialist agents, and Human-in-the-Loop workflows, with context management, memory, and tool-calling
• Develop MCP servers and tool integrations connecting AI agents to Teak's platform APIs and partner systems
• Orchestrate LLMs (Claude, GPT, Gemini, or similar) across the AI layer, selecting the right model per task and managing prompt and system-prompt strategies so agents present refund solutions in pre-approved, compliant language
• Build RAG pipelines that ground agent responses in Teak's policy and product data, with versioning and isolation that prevent hallucination on compliance-sensitive topics
• Implement guardrails that enforce compliant offer language, prevent unauthorized coverage claims, and meet regulatory requirements across Teak's markets
• Build evaluation frameworks to monitor, test, and continuously improve agent performance, reliability, and output quality
• Build and operate AI infrastructure on AWS, with structured logging and tracing for auditability and rapid issue resolution
• Contribute to backend services, APIs, and platform improvements in Python alongside AI work, applying clean code, testing, and strong engineering fundamentals
• Participate in code reviews, document agent system design and integration patterns, take part in Agile workflows, and join the on-call rotation
